Re: [PATCH 0/8] MR5896: win32u, server: Use the shared memory for GetClipCursor and GetAsyncKeyState.

[Grigory Vasilyev (＠h0tc0d3)]

@rbernon `win32u, server: Use the shared memory for GetClipCursor and GetAsyncKeyState.` The patch, along with the ntsync patches, caused my games to freeze when starting with a black screen.

Proton changed [win32u/input.c NtUserGetAsyncKeyState](https://github.com/ValveSoftware/wine/blob/25af144e4ac4e8de6bf4d8ea5d960af06...) in commit [38660173bb5aa5250ad414ac27517dce25b30a6a
](https://github.com/ValveSoftware/wine/commit/38660173bb5aa5250ad414ac27517dc...)

I simplified the NtUserGetAsyncKeyState function to look like this. I'm not sure if it's correct, but it's helped me.

```C
SHORT WINAPI NtUserGetAsyncKeyState( INT key )
{
    const desktop_shm_t *desktop_shm;
    struct object_lock lock = OBJECT_LOCK_INIT;
    NTSTATUS status;
    BYTE state = 0;

if (key < 0 || key >= 256) return 0;

check_for_events( QS_INPUT );

while ((status = get_shared_desktop( &lock, &desktop_shm )) == STATUS_PENDING)
        state = desktop_shm->keystate[key];

return (state & 0x80) << 8;
}
```
